No, the hellbore.weapon file will be indexing the deleted/wrongnamed sprites if you did it that way. If he also deleted SAW's weapon folder, that might work.
There is no .weapon file in this case since it is not a separate weapon. It functions the same way skin packs do, removing relevant sprites will be sufficient.
ah, perfect. I would suggest making that a little note on the main mod-page, as i'm sure its something that would deter some people, as i know i kind of ingored this mod at first because of it... but the portraits were just too good to give up XD
